Typesetting special right triangles

If you want to provide exercises for solving 30-60-90 and 45-45-90 triangles, feel free to use these LaTeX templates. Just omit or modify whatever values, then run it through pdflatex, then convert the PDF to a PNG or leave it as is. I like running pdftoppm to convert from PDF to PNG, but you can use ImageMagick or whatever.
